PyQt features and specs

Comprehensive UI library
PyQt provides a wide range of UI components, from basic widgets to advanced tools. This allows for the creation of highly sophisticated interfaces.
Cross-platform
Applications built with PyQt can run on different operating systems such as Windows, macOS, and Linux without requiring significant changes in the code.
Integration with Qt Designer
Developers can use Qt Designer to design and implement their UIs visually, which can then be seamlessly integrated with Python code in PyQt.
Powerful event handling
PyQt includes a highly efficient event handling system that makes it easy to manage user interactions and system events.
Good documentation and community support
PyQt is well-documented, and there's a large community of developers who can provide support and share resources.
Python-specific advantages
Leveraging Python's simplicity and readability, PyQt allows for rapid development and easy maintenance of applications.

Possible disadvantages of PyQt

License considerations
PyQt is available under the GPL and a commercial license. If you want to create proprietary software without open-sourcing your code, you need to purchase a commercial license.
Steep learning curve
While PyQt is powerful, it can have a steep learning curve for newcomers, particularly those who are not familiar with Qt and its paradigms.
Performance overhead
Being a binding for Qt, some operations may have extra overhead compared to native Qt applications written in C++.
Dependency on external libraries
PyQt relies on the Qt library, which means that you have to manage and distribute these dependencies along with your application.
Large binary sizes
Applications created with PyQt can result in relatively large binary sizes because of the included Qt binaries.
Fragmentation of tools
There can be fragmentation concerns, as PyQt must stay in sync with Qt, and different versions of Qt may introduce changes that are not immediately reflected in PyQt.

Which Python GUI library should you use? Comparing the Python GUI libraries available in 2023

Before the Qt Company (under Nokia) released the officially supported PySide library in 2009, Riverbank Computing had released PyQt in 1998. The main difference between these two libraries is in licensing. The free-to-use version of PyQt is licensed under GNU General Public License (GPL) v3 but PySide is licensed under GNU Lesser General Public License (LGPL). This means...

Python vs. JavaScript: Is It a Fair Comparison?
JavaScript is a clear winner in the category of mobile development. There are some niche frameworks to do mobile development with Python—like Kivy and PyQT—but pretty much nobody uses them. - Source: dev.to / over 3 years ago
what would be the best looking GUI framework to develop a desktop python application? (other than Tkinter)
If none of those are to your liking, you can use PyQT (or Pyside) but the learning curve is much steeper. Source: over 3 years ago
Is there a "Windows Forms" GUI designer for Python?
Also, there is the PyQt module which is a comprehensive set of Python bindings for the Qt GUI. It has Qt Designer. Source: about 4 years ago
Best way to install qutebrowser?
As for PyQt, that's developed entirely independently from Qt (by Riverbank Computing). The major/minor versions usually line up with the respective Qt releases (since the Qt release introduces new APIs, so a new PyQt release is needed to expose those to Python). However, it's versioned independently, and a new patch release of PyQt might be needed before/without Qt releasing a new patch release. For more details,... Source: over 4 years ago
